compareTo() Method in java wrapper class Example 2
Learn this program step-by-step with algorithm, source code, output and detailed explanation.
public class WrappercompareTo {
public static void main (String args[]){
Integer intObj1 = new Integer (25);
Integer intObj2 = new Integer ("25");
Integer intObj3= new Integer (35);
//compareTo demo
System.out.println("Comparing using compareTo Obj1 and Obj2: " + intObj1.compareTo(intObj2));
System.out.println("Comparing using compareTo Obj1 and Obj3: " + intObj1.compareTo(intObj3));
}
}
Comparing using compareTo Obj1 and Obj2: 0
Comparing using compareTo Obj1 and Obj3: -1

First understand the algorithm carefully. Then study the program line-by-line and compare it with the output. Finally, review the explanation section to strengthen your logic and programming understanding.
Rewrite the program without looking at the code. Modify values, conditions or logic and run it again. This helps improve confidence and strengthens coding skills much faster.
